DOOR-SPRING 'WINDER AND SET.

Application filed January 5, 151 1.

To all whom it may concern ie it known that I, SAUEZ. PAuLsoN, a citizenof the United States, residing at Brooklyn, in the count of Kings andState of flew ork, have invented certain new and useful Improvements inDoorSpring lVinders and Sets, of which the following is a specification.

My invention relates to improvements in door spring winders and sets,the object of the invention being to provide an improved connection forone end of a coiled spring such as commonly used on doors which permitsthe ready adjustment of the spring to give to the latter the desiredtension.

11 further object is to provide a device of this character which is ofextremely simple construction, neat and attractive in appearance, andstrong and durable in use.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and an rangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings: Figure 1 is a view in longitudinal sectionillustrating my improvements. Fig. 2 is a top plan view. Fig. 3 is aview in side elevation. Fig. 4. is a view in section on the line 4tet ofFig. 3. Fig. 5 is an end view of the spindle, and Fig. 6 is aperspective view of the locking key. 7

1 represents a bearing bracket having per forated ears 2 for thereception of securing devices, and said bracket is provided with alongitudinal bore of two diameters, the upper smaller diameterconstituting a cylindrical bearing 3, and the lower larger diameterconstituting a cylindrical casing a in which a circular series ofratchet teeth 5 on a spindle 6 are adapted to turn.

The spindle 6 at its lower end is provided with a longitudinal recess 7adapted to receive the inwardly bent end 8 of a coiled spring 9, thelatter positioned around the spindle and compelled to turn when thespindle is turned to adjust the spring as is well understood in thisart. It is, of course, to be understood that suitable means (not shown)will be provided for holding the lower end of the spring, but thisinvention has nothing to do with the particular support for the otherend of the spring.

The spindle 6 is provided with an annularflange 10 which closes thelower end of the Specification of Letters Patent.

casing t and bearsa'gainst the lower surface of the bracket 1. Theextreme upper end of the spindle is made angular as shown at 11 for thereception of wrench to turn the same, and below said angular portion 11,the spindle is made cylindrical as shown at 12 constituting a journal toturn in the bearing 3.

The casing portion a of the bracket 1 is provided with an integralrectangular extension 13 on its outer portion which extension isprovided with a slot 14, extending through the same and communicatingwith a longitudinal recess 15 in the interior of the casing. This recess15 and slot 1 1- are designed to accommodate my improved locking key 16which extends through the slot 14, and at its inner end is enlargedlongitudinally of the spindle as shown at 1'? so that shoulders 18 areformed at opposite sides of the key which engage the walls of recess 15and limit the outward movement of the key.

The extreme inner end of the key is beveled. or rounded as shown at 19.so that the turning of the spindle in one direction will cause theratchet teeth 5 to engage this beveled surface 19 and force the keylongitudinally and out of the way in recess 15.

After the spring is adjusted to the proper tension, the locking key 16is moved inwardly so that it engages the ratchet teeth as shown clearlyin 4, and securely holds the spring at the proper tension. In assemblingthe parts, the locking key is po sitioned in the casing, and then thespindle inserted, and after the parts are once assembled, the key cannotbe lost.

Various slight changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall Withinthe spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In combination, a bearing bracket having a longitudinal bore of twodiameters, and having a slot inthe wall of its larger diameter, aspindle having a journal fitting the smaller diameter and having aseries of teeth adapted to turn in the larger diameter of the bearing,said spindle constructed at one end to facilitate its rotary movement,

and at its other end constructed for connection with a coiled spring,and locking key movable through the said slot in the larger diameter 01the bearing bracket and adapted to lock with the teeth, substantially asdescribed.

2. In con'ibiiiiation, a bearing bracket having a longitudimil. bore oftwo diameters, a spindle having a journal fitting the smaller diameterand having a series of teeth adapted to turn in the larger diameter ofthe bearing, said spindle constructed at one end to facilitate itsrotary movement, and at its other end constructed for connection with acoiled spring, said bracket having a slotted extension, and a recess atthe inner end of the slotted extension, a locking key projecting throughthe slotted extension and having an enlarged inner end movable in therecess, said key having a beveled inner end adapted to lock with saidteeth, substantially as described.

In combination, a bearing bracket having a longitudinal bore of twodiameters, a spindle having a ournal fitting the smaller diameter andhaving a series of teeth adapted to turn in the larger diameter of thebearing, said spindle constructed at one end to facilitate its rotarymovement, and at its other end. constructed for connection with a coiledspring, said bracket having a slotted extension, and a locking key insaid slotted extension adapted to engage the said teeth, said largerdiameter of bore extending to one end of the bracket, and said spindlehaving an annular flange bearing against the lower end of the bracketand closing said larger diameter of bore, substantially as described.

4. In combination, a bearing bracket having a longitudinal bore of twodiameters, a

spindle having a ournal fitting the smaller diameter and having a seriesof teeth adapted to turn in the larger diameter of the bearing, saidspindle constructed at one end to facilitate its rotary movement, and atits other end constructed for connection with a coiled spring, saidbracket having a slotted extension, and a recess at the inner end of theslotted extension, a locking key projecting through the slottedextension and having an enlarged inner end movable in the recess, saidkey having a beveled inner end adapted to lock with the said teeth, saidlarger diameter of bore extending to one end of the bracket, and saidspindle having an annular flange bearing against the lower end of thebracket and closing said larger diameter of bore, substantially asdescribed.

5. in combination, a bearing bracket, a spindle mounted to turn in thebearing bracket, an annular flange on the spindle, said spindle at itsend having a longitudinal groove adapted to receive the inwardly bentend of a coiled spring, a circular series of ratchet teeth on thespindle located within the bearing bracket, a movable key adapted tolock with said teeth, said key having an enlarged inner beveled endadapted to engage with the teeth when the latter are turned in onedirection and to be moved by the teeth when the teeth are turned in theopposite direction, and said spindle at one end projecting beyond thebearing bracket and made angular, substantially as described.

In testimony whereof I haye signed my name to this specification in thepresence of two subscribing witnesses.
